Abstract

The main aim of the investigation is to develop new nano-based PCM (phase change materials) establishing thermal energy storage for catering cooling needs in tropical buildings. PCM’s lag with their thermal properties like thermal conductivity, latent heat of capacity etc. To enhance its properties generally, nanoparticles are dispersed in PCMs. The present work deals with the synthesis of TiO2 nanoparticles using sol-gel chemical method and characterizing particle size,
shape and its morphology. The as-prepared TiO2 nanoparticles were dispersed with different wt. % in Rubitherm 21 type PCM. Then, nano based PCM’s were tested for its melting, freezing, latent heat characteristics and concluding for compact ability with building applications to cater cooling needs.
